The film shows the difference in temperature of the subsurface and that works well!
Upon removal of gas, in the normal use of the bottle cools
remaining liquid from gas in the bottle. The result is a temperature difference
the upper, empty bottles part that has the ambient temperature.
This limit is the indicator displays (lateral displacement of the stroke)
if these staples in height on the bottle. That's the level.
At the end of the gas sampling the temperature down slowly like again
the ambient temperature and is then read no more.
the magnetic holding force is sufficiently high when the film
attached flat to the substrate, not on the weld seam in the middle.
with me the gas level indicator fulfills its function very well
